Tensorflow Implementation of Expressive Tacotron

Hi there 👋

I'm writing to inform that I'm not allowed to introduce myself as "I work for Kakao Brain." any more. I left Kakao Brain, where I've put my heart for the last four years, and began a new journey on my own. Luckily, I'm not alone on that road not taken. I'm with five great co-founding members--all of them were my team mates at Kakao Brain. We named our startup TUNiB, inspired by the popular animation character (https://octonauts.fandom.com/wiki/Tunip_the_Vegimal). We are still at the very early stage, preparing for IR. Please support us as well as Kakao Brain. You can reach us/me at my email: either [email protected] or [email protected].

Best,
Kyubyong

expressive_tacotron's Issues

It seems that the prosody not transferd

I have checked your sample result of 420k trainning,and tried align the referr sound and the target sound,it seems that they are much different.
So i really confused how the auther of the paper done that.Maybe he used so large data set containing 100+ hours so that it can get good result.

Can someone share the pretrained model ?

Just like the tacotron can someone share the pretrained model(on LJ Speech Dataset) for this as well?

It would be great if you could release some audio that generated by your implementation.

I really want to know the audio quality will be achieved after 200 steps.

About emotional control

In addition to rhythm, can this model control the emotion of the audio? Is there an example?

How to find out when training went wrong?

Thank you very much for your contribution. I have trained the model on LJ Speech for 835k. However, the results are not as good as the samples you provided for 420k. Maybe some problem with my training? Below you can find the attention plot and the sample audio at 835k. What kind of attention plot signals a good checkpoint for the synthesizer?

And the progress was like this:

The samples synthesized from this checkpoint can be found here:
https://www.dropbox.com/sh/n5ld72rn9otxl7a/AAACyplZMtxiYtuUgvWN8OGaa?dl=0

Also, the trained model (checkpoint), is uploaded here:
https://www.dropbox.com/sh/ks91bdputl5ujo7/AABRIqpviRDBgWuFIJn1yuhba?dl=0

Also, I was wondering if you have any plans to release your trained model.

Another thing is the tf.save keeps the last 5 checkpoints by default, and the wrapper used here (i.e. tf.train.Supervisor) does not easily allow changing max_to_keep property of the saver.

PS. The hyperparameters are kept as default.

getting file not found error when i run train.py even when i m having file

no checkpoits after running train.py

@Kyubyong I'm able to run train.py successfully, but there is no checkpoints available in logdir, so unable to run synthesize.py

I have changed parameters such as:
lr = 0.9 # Initial learning rate.
logdir = "logdir"
sampledir = 'samples'
batch_size = 16

and also i made some changes in train.py

if name == 'main':
g = Graph(); print("Training Graph loaded")

sv = tf.train.Supervisor(logdir=hp.logdir, save_summaries_secs=60, save_model_secs=0)
with sv.managed_session() as sess:

    if len(sys.argv) == 2:
        sv.saver.restore(sess, sys.argv[1])
        print("Model restored.")

    #while 1:
        for _ in tqdm(range(g.num_batch), total=g.num_batch, ncols=70, leave=False, unit='b'):
            _, gs = sess.run([g.train_op, g.global_step])

            # Write checkpoint files
            if gs % 100 == 0:
                sv.saver.save(sess, hp.logdir + '/model_gs_{}k'.format(gs//100))

                # plot the first alignment for logging
                al = sess.run(g.alignments)
                plot_alignment(al[0], gs)

        #if gs > hp.num_iterations:
            #break

print("Done")

An error of TypeError while running LJSpeech-1.1

Thanks for your contribution. 👍

I follow the steps of Training: Run python train.py.

However, I got this error: :(
0%| | 0/409 [00:00<?, ?b/s]2018-04-08 11:58:13.819432:

could not find eval.py anywhere

from where shall i run step 3 as mentioned by you :

STEP 3. Run python eval.py regularly during training.

How to test the trained model with some real sentence?

Thanks for your contribution.

I got the good alignment result since 23k steps,

but I cannot find eval.py, and how can i test the trained model with real sentence i type?

NotFoundError: Restoring from checkpoint failed.

python synthesize.py

tensorflow.python.framework.errors_impl.NotFoundError: Restoring from checkpoint failed. This is most likely due to a Variable name or other graph key that is missing from the checkpoint. Please ensure that you have not altered the graph expected based on the checkpoint. Original error:

Hello, how fast have you achieved this, and how long have you been training this network based on your parameters?

ValueError: Cannot feed value of shape (16, 188) ...

I have trained the model on LJ Speech for around 670k steps. When using python synthesize.py command I have received this error.
